News July 16, 2015 - Indonesian copper smelter Gresik has shut down due to a technical problem and it is not clear when the smelter will reopen, a spokesman at majority owner Mitsubishi Materials Corp said on Thursday.Takuya Kitamura said that the shutdown at the smelter was due to a broken pipe system, but he was not able to give a timetable for how long the outage would last.Mitsubishi Materials owns 60.5 percent of the operator of the facility, PT Smelting. The Indonesian unit of U.S.-based Freeport-McMoRan Inc holds a 25 percent stake.Two sources with knowledge of the shutdown said the plant has already been shut for several weeks, and that they expected the closure to last for at least one more.The Gresik smelter produced 230,000 tonnes of refined copper last year running at about 75 percent of its capacity."They were hoping to get it fixed, but they couldn't. Another week or so and it would nearly be a month," said a trader in Asia."It hasn't hurt them too much because of the slowdown in Indonesia, during Ramadan, when people tend to push back on deliveries. Still, it's gone on long enough now that ... it probably will affect deliveries."Kitamura was not able to say whether the company was looking for alternatives for themselves or their customers for sourcing replacement supply.Traders said that customers were unlikely to be hurt, since PT Smelting could easily buy metal from an amply supplied spot market to replace any contracted shipments.

- Newmont Mining Corp's Indonesian copper export permit will not be renewed beyond March 19 unless it strikes a deal with Freeport-McMoRan Inc to invest in the latter's planned smelter, a mines ministry official said on Monday."For an export permit extension for Newmont, we are still awaiting an agreement between Freeport and Newmont," Coal and Minerals Director General Sukhyar told a news conference."It will depend how serious Newmont's commitment to co-operate with Freeport is and how much they will share the investment," Sukhyar said.Indonesia has been in talks with miners about their plans to develop domestic smelting and processing facilities.Early last year, Jakarta put in place export restrictions aimed at forcing mining firms to develop smelting and processing facilities so that Indonesia could refine all of its raw ores and concentrates."We share the government's stated goal of increasing value-added mineral processing in Indonesia," said Newmont spokesman Omar Jabara."As part of our MoU (memorandum of understanding) with Freeport, we continue working with them in support of their plans to develop a smelter. (Newmont) also has concentrate supply agreements with two Indonesian companies planning to build domestic smelters."Although fellow U.S.-based miner Freeport is pushing ahead with expansion plans at Indonesia's sole copper smelter at Gresik, Newmont has said multiple studies show its Batu Hijau mine cannot sustain a smelter on its own.The Indonesian government has long urged the companies to cooperate on a smelter.After a fractious nine-month export tax dispute, Newmont signed a deal with the government last year that allowed for the resumption of copper concentrate exports. But this agreement is set to end unless Newmont can show it is serious about domestic processing."If they really commit, they will be given an export permit extension," Sukhyar said. "The time limit for us to give an export permit extension is March 19."Newmont and Freeport account for 97 percent of Indonesia's copper output."We continue to advance our discussions with the government of Indonesia on an agreement for our long-term operating rights," said Freeport spokesman Eric Kinneberg, adding the talks include such issues as royalties and taxes, domestic processing and refining, divestment, and local content."In parallel, we are advancing plans to construct new smelter capacity in Indonesia. A site has been identified and we are actively engaged in discussions on technical, commercial and partnership arrangements."

-  Indonesia has dropped its demand that Freeport-McMoran Inc build a $1.5 billion copper smelter in Papua province, saying a regionally owned enterprise would take on the project instead, website Detik.com reported, quoting the mining minister.The ministry in December said Arizona-based Freeport, which runs the world's fifth-largest copper mine in Indonesia, should agree to build the Papua smelter in five years if it wanted a mining contract extension beyond 2021.The latest decision could ease pressure on Freeport, which has already agreed to a $2.3-billion expansion by 2017 of its copper smelting facility in East Java, currently the only one in the country.The government has been pushing the company to comply with rules that force miners to process and refine minerals domestically."If Freeport is burdened in two locations it would be uneconomical," Energy and Mineral Resources Minister Sudirman Said said on Sunday, according to the Detik website.A regionally owned enterprise would build the Papua smelter and could team up with other investors on the project, the ministry said in a document obtained by Reuters.An investor from China has already approached the Papua administration, Detik's report cited Said as saying, without providing details."A smelter on its own is not economical so we are building an (industrial) zone to make it more attractive," Said said.A ministry spokesman was not immediately available to confirm the comments.The 650-hectare industrial zone in Papua's Mimika area is not far from Freeport's concentrate pipeline and already has a port and eletrical infrastructure, according to the document.The zone will also include a cement packaging plant, a liquefied petroleum gas filling plant, a fertilizer plant and a petrochemicals plant."This is a win-win solution," Said said, adding that Freeport would be contractually required to supply copper concentrate to the Papua smelter."Whoever is tasked to build the smelter in Papua, Freeport Indonesia will form a business-to-business contract with them to supply concentrate," Freeport Indonesia CEO Maroef Sjamsuddin said in the document.Freeport is expected to produce 2 million tonnes of copper concentrate from its Indonesian operations in 2015, up from 1.4 million tonnes in 2014.Indonesia aims to develop 4.5 million tonnes of copper concentrate processing capacity nationally, Said said, up from 1.2 million tonnes at present.
